ADJUSTABLE SHELF-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 754,816 ,`vdated March 15, 1904. Application tiled April 30, 1F02. Serial No. 105,388. -lvll'o model.)

T 0 @ZZ whom, it 72mm/ concern.

Be itknown that I, EDWARD G. SCHRrnPnR, a citizen of the United States, residing at' Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful lImprovements in Adjustable Shelf-Supports,

of which the following is a specification.

lt is the object of my invention to provide new and useful improvements in ad justablc shelf-supports suitable for shelves, which may also take the form of filing units and the like in cases, such as book or ling cases, store or other fixtures, racks, and the like; and my invention consists 1n means whereby the shelf the sides o f the fcase and the shelf, in means aiding in holding the sides against sidewisev is supported and aiding tore'latively position displacement or bulging, and, further, in the parts and in the construction, arrangement, and combinations of parts hereinafter more fully` described and claimed.

The subject-matter' claimed in the present application is also shown and described in my applications, Serial Nos. 92,461, 92,462, and 92,463, filed February 3, 1902. I have also shown, described, and claimed an adjustable shelf-support in another application of even.

date herewith, being SeriaLNo. 105,389. diftering in detail from the form of adjustable shelf-support herein shown and described, to all of whichapplications' reference isrespectfully made.

In the drawings, Figure 1 represents aperspective view of my improved device in connection with a case with the top and bottom and frontedges of the case broken away. Fig. 2 is a vertical section taken through the sides of the case and shelf on a line corresponding to the line a: al of Fig. 4 with the shelf in raised position and showing the sides in spread relation. Fig. 3 is a similar view showing the shelf seated and the sides in proper relative position. Fig. 4 is a plan view of my improveddevice with the side shown in horizon tal cross-section and the shelf omitted. Fig. 5 is a perspective view of the connected support. Fig. 6 is a bottom view of the shelf, showing receiving-mortises for the tongues of the-supports. Fig. 7 is a perspective view of a single support; and Fig. 8

- a vertical' section taken on a line correfy spending to the line .fn :z: of Fig. 4, but show-v ing as a modification a plate taking into the shelf-mortises. l

1 represents the back of the case, and Qtlie sides. 3 is a shelf. Strips 4 are secured to .he sides, the strips having openings 5 andV may'also have a groeve. 6, extending longi tudinally of the strips and receding outn'yartllgi from the insideof the case. In the depressed portion of each groove the openings 5 are located. l The strips are suitably secured to the.

caseand a. clearance-groove 'I is located in rear of the openings. The strips are preferably countersunk into the sides .in grooves 8', so as to leave the outer edges of the strips iush with the sides. Supports 9 are adapted to support the shelf. 'lhe support preferably comprises a hook 10, adapt-ed to take through one of the openings, having a lip 11, adapted to engage the rear of the strip 4, and a de pending shank 12, adapted to be received by the groove 6, and a ledge 13, adapted to receive the shelf. A depending portion -or tail 14 takes against the strip, preferably in the groove 6, and a finger 15 extends above the ledge 13, preferably at an angle 'to the strip, for forming a Wedge or inclined face adapt-ed to draw` the shelf and the sides together. Each side is preferablv'provided witha plurality of strips, 'usually one toward the rear and one toward the front of the shelf, Aeach strip having a support9 for each shelf. The The supports may be connected by a web 16. A rib 17 may be provided for the support. The shelves have recesses 18 for receiving the fingers of the supports. The side of the mortise toward the end of the'shelf may he inclined, as vshown at 19, to correspond to the inclination of the finger. The end of the shelf may also be rabbetted, as shown at 20, for receiving the support. The mortise for the shelf may also he provided with a faceplate 21, against which the linger may take. Means are thus provided whereby the shelf coming in connection with the support, through pressure on the shelf, draws the sides together in case they are buigcd. Means are provided for positioning the sides properly by a wedging action, and simple and effective means are provided for limiting'sidewise disof wood or, if desired, of other material.

A The face-plate 21 may be made of metal, or,

if desired, the finger .may impinge against the wood of theshelf.

I clairn- 1. The combination with a pair of sides and a shelf, of shelf-strips secured to and extending up and down' on each side at the inner face thereof, and `shelf-supports releasably engaging said shelfst-rips at various elevations and .extending from said sides under the ends of the shelf, said shelf-strips having a groove and said supports having adownwardly-project-ing shank extending intosaid groove, said shelf and supports having interengaging in'- clined faces acting to draw the sides toward' the shelf while seating the shelf with relation tothesides. Y I l 2. The combination with a pair of sides and ashelf, of shelf-strips secured to and extending up and down on eaehside at the inner face thereof, and shelf-supports releasa-bly engagingsaid shelf-strips at various elevations and extending from said sides under the ends of the shelf, said shelfstrips having agroove and said supports having a downwardly-projecting halnk extending into said groove, and means b tween. the shelf and'sides acting to draw the\sides inwardly While seating the shelf, said and shelf adjustable up and.

3. The combin tion of a pair of sides each having a pair of groovesin its inner face, four shelf-strips, one ineach of said grooves and extending up and down on the side, each of said shelf-strips having a. groove in its outer face and a iiange at each side of said groove' projecting sideivardly from said groove in sub stantialy the plane of the inside face of said side, a pair of shelf-supports releasable from said shelf and sides, one at each end of the I --shelf extending beyond said end from said shelf-strips, said shelf-strips having openings for receiving said supports and said shelf-supports having shanks taking into said grooves in said shelf-strips.

4. The combination of `a pair of sides each having a pair of grooves in its inner face, four shelf-strips, one 1n each of said grooves and ext-ending up and-down on the side, each of said shelf-strips having a groove in its outer face and a flange at each side of said groove projecting sldewardly from said groove in sub- Y stantially the plane of the inside face of said side, a pair of shelsupports releasable from 'said shelf and sides, one at'each end of the shelf extending beyond said end from said shelf-strips, said shelf-strips having openings 'or receiving said supports and said shelf-snpports having Shanks taking into said grooves in said shelf-strips, with means between' the shelf and shelf-support for relative-ly' drawing 4the shelf and side toward each other while seat ing the shelf. c y

5. In an adjustable shelf-supporting device the combination with the sides of a case and a.

`shelf therefor, said sides having grooves 7 and ings 5, said supports further having' depending shank 12 and depending tail litaling into the said gro'ove 6 and also having a finger 15, the shelf having an opening 18 the outer wall -8, shelf-strips 4 having grooves 6 and openings 5 and also having sidewardly-extending anges located in the grooves 8,' supprts 9 hav- Aing a hook 10 arranged to engage in'said open'- of which is arranged to engage said finger 15, v

' and constructed and arranged for relatively drawing the shelf and side toward each other when seating the shelf.

In testimony whereof Ihave signed my name hereto in the presence oftwo subscribing witnesses.
